Maybe you know the story of Alice in Wonderland. In her dream Alice was shaking an ugly queen but when she woke up she realized that she wasn’t holding the queen but her kitten.
Exercise: Draw something that Alice is holding when she is still dreaming or when she has just woken up. For the construction of the hand, assisting lines are useful (below left and right). If the hands are holding something larger, draw the arms a little further apart (right). Make sure that the fingers really seem to enclose the object that is being held.
You can even hold scary or dirty things in a drawing. This green monster head is now a bit defenseless and helpless.
